The Daily Mail says in a sensational twist to the tale of Mourinho's departure, Grant contacted the boss of Israel's coaching set-up at the end of last week and said: "I need a Pro Licence - and I need it in a hurry."
Grant first made contact with Amnon Raz, Israel's equivalent of League Managers' Association chief John Barnwell, six months ago and asked about the procedure for a Pro Licence but decided against taking it any further.
There was a different tone about his latest call a week ago, according to informed Israel Federation sources, as he quizzed Raz about the quickest way of obtaining a certificate that is viewed as a necessity for managing in the Premier League.
Former Israel skipper Avi Nimni added: "His appointment may have surprised many people, but not me.
"I am in daily contact with Grant, and this move has been on the go for a long time.
"You have to be beside Abramovich and Grant to understand the connection between them."
Ex-Israel Under-18 coach Raz is due in London next week to discuss Grant's options and has also recruited Federation president Avi Luzon to try to hasten the qualification process.
